METHOD OF AND APPARATUS FOR DISINTEGRATING PAPER STOCK.

wtpplication filed July 25,

To all whom it may concern:

\ Be it known that I, MILTON C. J. BILLING- HAM, a citizen of the United States, residing at the city and county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Methods of and Apparatus for Disintegrating Paper Stock, of which the following is a specification.

This invention relates to improvements in paper stock treating machines.

My improved stock treating -machine is especially designed by me for use in disintegrating old papers for use as paper stock and for use in deinking such stock.

- The main objects of this invention are:

First,-to provide an improved disintegrating or defibreing machine in which the fibres are effectively separated or disintegrated without a grinding or abrading action.

Second, to provide an improved stock treating machine in which all of the stock is effectively acted upon.

Third, to provide an improved stock treating machine which is well adapted for disintegrating or defibreing printed papers, also for treatment thereof with deinking solutions.

Further objects, and objects relating to structural details, willdefinitely .appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following, specification.- The invention is clearly defined andpointed out in the claims.

A structure which is a preferred embodiment of my'invention is clearly illustrated inthe accompanying drawing, forming a part of this specification, in which:

Fig. I is a detail side view. of my improved stock' treating machine.

Fig. II is a vertical section on a line corresponding to line 2-.2 of Fig. I, certain parts being shown in full lines for convenience in illustration.

Fig. III is a horizontal section on a line corresponding to line 3-3 of Fig. II.

Fig. IV is a detail horizontal section on a line corresponding to line 4-4 of Fig. II.

Fi V, is a detail vertical section correspon ing to that of Fig..II, showing amodified embodiment of iny invention.

FigJVI is a detail side elevation ofthe discharge connections for the embodiment shown in'Fig. V.

Patented July 1918. Serial No. 246,695.

In the drawing similar reference charac ters refer to similar parts throughout the several views, and the sectional views are taken lookingin the direction of the little arrows at the endsof the section lines.

Referring to the drawing: In the embodiment illustrated I provide a tank 1 supported in an upright position on a suitable base 2. In this embodiment the bottom 3 is in the form of an inverted cone terminating in an annular trough 4. A cone 5 projects upwardly from the inner edge of this trough well to the top of the tank.

On the top of the tank I mount a chamber 6 having a bottom 7 shaped like an inverted cone with a central discharge opening 8, the tip of the cone5 being central ofthis openingand close thereto. On the chamber bottom 7 I arrange blades or plates 9 so as to impart a swirling or rotary motion to the material as it is discharged through the opening 8, the plates being disposed radially and preferably having their ends curved in the same direction as shown in Fig. IV. At the upper end of the cone I provide a plurality of deflector plates. 10, the plates being radially disposed relative to the cone, their inner ends in .the embodiment shown in FigsLII and III being secured to the cone and their outer ends bolted to the tank. These plates are transversely inclined all in the same direction so as to impart a rotary movement to the material passing downward through the tank. To insure a uniform distribution of the material by the blades they are provided with transverse tapered corrugations 11, that is, the corrugations extend from the front edges of the *plates partially across the same. On the rear edges of the plates are curved flanges 12 which also aid in giving the desired rotary motion to the material within the tank.

l/Vith this arrangement the settling and forming of streams or courses within the tank is prevented, all of the material being kept in circulation.

Within the chamber 6 are nozzles 13 disposed oppositel so that the jets or streams indicated at14= lmpinge preferably centrally of the chamber. Thenozzles are connected by the pipes lii to the discharges of the rotary pumps 16, the intakes 17 of the pumps being connected to the discharge trough 4 of the tank. Valves 18 control these intakes.

rlrives both pumps. A batch, of stock is,

lInv the structure illustrated a motor 19' introduced into thetank through the pipe 20 and when 'fully treated through the pipes 21. With the parts thus -arranged the batch of stock is repeatedly cir- 'culated through the nozzles and the llIlPlIlging streams effectively tear up and forming of streams orcourses is prevented 5 sothat all of the stock is uniformly treated.

- My improved machine is espec1a'lly'well adapted for the treating of stock with dei inlnng solutionsas the stock is not only uniformly fectively disintegrateds In' the modification shown in Figs. V and the conical bottom 22 of the tank extendsto a central outlet coupling 23 in the pipe 24 leading to the pumps 16- The discharge in this-embodiment is at 25. The'cone 26 issupported on feet 27 with its lower edge in a spaced relation to the bottom so'that the material may HOW to the central outlet. In this construction'the distributing plates 28 form parts of the wheel, the outer ends of the'plates being secured to a rim 29 carried by' rollers 30, the inner ends ofthe plates being secured to-a rotatable top section 31 l o f-the cone. This rotating section 31 ofthe "spindle 34'. "As the stock cone is supported by the bearings 32 and the passes downwardly about the cone it strikes these plates 28 cansing the rotation thereof, thus securing the rotary movement or agitatinn of the ma terial in the tank. The embodiment shown in Fig. II, however, has the advantage of dition, that is, the. fi

being less complicated mechanically. By

the aid of this apparatus I am enabled to dis-. .integrate fibrous material, such as print its original pulp conres are not shortened or broken up as by grinding .or coming in contact with a hard unyielding surface as the disintegration is effected by the pulling or tearing'action While the material is entirel suspended in the carrying liquid-\- I ave illustrated and descrlbedtwo embodiments of my invention, which I believe will enable those skilled in the art to which my invention relates to embbdy or adapt the paper, to substantiall same as conditions. or uses may render de-f sirable. Having thus described my invention, what I claim as new and desire to secure by LettersPatent, is: y s
